If she's not pushing any of this stuff on you, and has been helpful, I seriously would not be bothered by it. I also don't think having different viewpoints on whatever, from politics to religion to alternative medicine to science, can keep people from "getting" and helping each other (provided the different viewpoints are of the non-murderous type). It's harder, sure, but worth it to get past the differences. And sounds like she might be worth it?

I'd also like to float the possibility that some of the things you mention are how she takes care of herself, so that she can be in the best possible state herself to do her job.
